New Studies Of HIV Infection

New Studies Of HIV Infection.
A recently discovered, warlike stretch of HIV leads to faster development of AIDS than other HIV strains, according to a new study. More than 60 pandemic strains of HIV-1 exist. This new strain has the shortest space from infection to the development of AIDS, at about five years, according to researchers at Lund University, in Sweden.

The novel strain is a fusion of the two most common strains in Guinea-Bissau, a small country in West Africa. It has been identified only in that region. When two strains join, they manifestation what's called a "recombinant. Recombinants seem to be more hearty and more aggressive than the strains from which they developed," doctoral student Angelica Palm said in a Lund University intelligence release.

The Relationship Between Heart Disease And Dementia Exists

The Relationship Between Heart Disease And Dementia Exists.
Older women with consideration contagion might be at increased risk for dementia, according to a new study. Researchers followed nearly 6500 US women, grey 65 to 79, who had healthy brain function when the study started. Those with goodness disease were 29 percent more likely to experience mental decline over leisure than those without heart disease. The risk of mental decline was about twice as high among women who'd had a sensibility attack as it was among those who had not.

Women who had a heart bypass operation, surgery to transfer a blockage in a neck artery or peripheral artery disease also were at increased risk for mental decline. Heart infection risk factors such as high blood pressure and diabetes also increased the gamble for mental decline, but obesity did not significantly boost the risk, according to the study, which was published in the Dec 18, 2013 emergence of the Journal of the American Heart Association. "Our study provides further new testify that this relationship between heart disease and dementia does exist, especially among postmenopausal women," study founder Dr Bernhard Haring said in a journal news release.

Heartburn Causes A Deficiency Of Vitamins

Heartburn Causes A Deficiency Of Vitamins.
People who peculate trustworthy acid-reflux medications might have an increased risk of vitamin B-12 deficiency, according to new research. Taking proton force inhibitors (PPIs) to ease the symptoms of excess stomach acid for more than two years was linked to a 65 percent heighten in the risk of vitamin B-12 deficiency. Commonly second-hand PPI brands include Prilosec, Nexium and Prevacid. Researchers also found that using acid-suppressing drugs called histamine-2 receptor antagonists - also known as H2 blockers - for two years was associated with a 25 percent rise in the chance of B-12 deficiency.

Common brands incorporate Tagamet, Pepcid and Zantac. "This study raises the question of whether or not people who are on long-term acid repression need to be tested for vitamin B-12 deficiency," said study author Dr Douglas Corley, a fact-finding scientist and gastroenterologist at Kaiser Permanente's division of research in Oakland, California Corley said, however, that these findings should be confirmed by another study. "It's unfeeling to place a general clinical recommendation based on one study, even if it is a large study.

Vitamin B-12 is an important nutrient that helps agree blood and nerve cells healthy, according to the US Office of Dietary Supplements (ODS). It can be found result in meat, fish, poultry, eggs, milk and other dairy products. According to the ODS, between 1,5 percent and 15 percent of Americans are scarce in B-12. Although most forebears get enough B-12 from their diet, some have trouble absorbing the vitamin efficiently.

A deficiency of B-12 can cause tiredness, weakness, constipation and a diminution of appetite. A more serious deficiency can cause balance problems, honour difficulties and nerve problems, such as numbness and tingling in the hands or feet. Stomach acid is beneficial in the absorption of B-12 so it makes sense that taking medications that reduce the amount of stomach acid would curtail vitamin B-12 absorption.

More than 150 million prescriptions were written for PPIs in 2012, according to offing information included in the study. Both types of medications also are available in lower doses over the counter. Corley and his colleagues reviewed details on nearly 26000 people who had been diagnosed with a vitamin B-12 deficiency and compared them to almost 185000 society who didn't have a deficiency.

Risks And Benefits Of Treatment Kids' Ear Infections With Antibiotics

Risks And Benefits Of Treatment Kids' Ear Infections With Antibiotics.
Antibiotics may servant more children with on the qui vive ear infections recover quickly, but the drugs also come with the endanger of side effects, concludes a new analysis of previous research. Between 4 and 10 percent of children know side effects, such as diarrhea or rash, from antibiotic use, according to the analysis. "If you have 100 fit children with an acute ear infection, about 80 would get better with just over-the-counter pest and fever relief - but if you treated all 100 of those kids with antibiotics, you would quickly smoke 92 of them.

But, the number of children who would benefit is similar to the number of children who would experience stand effects like diarrhea and rash," explained the study's lead author, Dr Tumaini Coker, an aide-de-camp professor of pediatrics at the Mattel Children's Hospital and the David Geffen School of Medicine at University of California Los Angeles. "Parents genuinely have to weigh the risks and benefits of care when a child has an ear infection".

In addition to finding that early prescribing of antibiotics offers some improve in the treatment of ear infections, the researchers also found that newer, name-brand antibiotics didn't appear to be any more efficacious than old stand-bys, such as amoxicillin, which are often generic and less expensive. "Parents need to know that when a child gets an attention infection, antibiotic treatment might not always be the best option," said Coker, who is also a researcher at the RAND Corporation, a non-profit enquire institute. "And, for most healthy children with a newly diagnosed ear infection, we couldn't realize any evidence that newer antibiotics worked any better than older ones".

Acute ear infection (otitis media) is the most worn out reason that antibiotics are prescribed for children in the United States, according to CV information in the study. The average cost of an ear infection is $350 per child, which ends up costing the express health-care system about $2,8 billion annually.

The Main Cause Of Obesity In The USA Are Sugary Drinks, French Fries, Potato Chips, Red Meat

The Main Cause Of Obesity In The USA Are Sugary Drinks, French Fries, Potato Chips, Red Meat.
The edict to feed-bag less and use more is far from far-reaching, as a additional analysis points to the increased consumption of potato chips, French fries, sugary sodas and red victuals as a major cause of weight gain in plebeians across the United States. Inadequate changes in lifestyle factors such as television watching, exert and sleep were also linked to gradual but relentless weight gain across the board. Data from three take studies following more than 120000 healthy, non-obese American women and men for up to 20 years found that participants gained an ordinary of 3,35 pounds within each four-year period - totaling more than 16 pounds over two decades.

The unrelenting value gain was tied most strongly to eating potatoes, sugar-sweetened beverages, red and processed meats and ladylike grains such as white flour. "This is the paunchiness epidemic before our eyes," said study author Dr Dariush Mozaffarian, an companion professor in the department of epidemiology at Harvard School of Public Health and the division of cardiovascular pharmaceutical at Brigham and Women's Hospital and Harvard Medical School.

So "It's not a small segment of the inhabitants gaining an enormous amount of weight quickly; it's everyone gaining weight slowly. I was surprised how steadfast the results were, down to the size of the effect and direction of the effect". The mug up is published in the June 23, 2011 issue of the New England Journal of Medicine.

Participants included 50422 women in the Nurses' Health Study, followed from 1986 to 2006; 47898 women in the Nurses' Health Study II, followed from 1991 to 2003; and 22,557 men in the Health Professionals Follow-Up Study, tracked from 1986 to 2006. The researchers assessed unfettered relationships between changes in lifestyle behaviors and charge changes within four-year periods, also judgement that those doing more material motion translated into 1,76 fewer pounds gained during each time period.

Participants who slept less than six hours or more than eight hours per end of day also gained more within each study period, as did those who watched more television an standard of 0,31 pounds for every hour of TV watched per day. And fast scoff addicts, beware: Each increased daily serving of potato chips alone was associated with a 1,69 pound-weight pull away every four years.

Risky Behavior Comes From The Movies

Risky Behavior Comes From The Movies.
Violent moving picture characters are also favourite to drink alcohol, smoke cigarettes and engage in sexual behavior in films rated pertinent for children over 12, according to a new study. "Parents should be aware that youth who watch PG-13 movies will be exposed to characters whose savagery is linked to other more common behaviors, such as alcohol and sex, and that they should weigh whether they want their children exposed to that influence," said study lead author Amy Bleakley, a management research scientist at the University of Pennsylvania's Annenberg Public Policy Center. It's not apprehensible what this means for children who watch popular movies, however.

There's intense debate among experts over whether intensity on screen has any direct connection to what people do in real life. Even if there is a link, the new findings don't mention whether the violent characters are glamorized or portrayed as villains. And the study's resolution of violence was broad, encompassing 89 percent of popular G- and PG-rated movies. The study, which was published in the January circulation of the journal Pediatrics, sought to find out if violent characters also tied up in other risky behaviors in films viewed by teens.

Bleakley and her colleagues have published several studies lesson that kids who watch more fictional violence on screen become more violent themselves. Their research has come under devour from critics who argue it's difficult to gauge the impact of movies, TV and video games when so many other things power children. In September 2013, more than 200 people from academic institutions sent a affirmation to the American Psychological Association saying it wrongly relied on "inconsistent or indistinct evidence" in its attempts to connect violence in the media to real-life violence.

For the new study, the researchers analyzed almost 400 top-grossing movies from 1985 to 2010 with an sensitivity on violence and its connection to libidinous behavior, tobacco smoking and alcohol use. The movies in the sample weren't chosen based on their implore to children, so adult-oriented films little seen by kids might have been included. The researchers found that about 90 percent of the movies included at least one twinkling of an eye of violence involving a main character.

Cardiologists Recommend The Use Of Heart Rate Monitors

Cardiologists Recommend The Use Of Heart Rate Monitors.
A largely hand-me-down type of heart monitor may provide a simple way to predict a person's hazard for a common heart rhythm disorder called atrial fibrillation, according to a new research Dec 2013. Researchers found that people who have a greater number of heart contractions called early atrial contractions have a substantially higher risk for atrial fibrillation. These types of contractions can be detected by a 24-hour Holter monitor.

Premature atrial contractions are beforehand heartbeats that occur in the two uppermost chambers of the heart. A Holter monitor is a portable device that continuously monitors the electrical pursuit of a person's heart. The study included 1260 people, superannuated 65 and older, who had not been diagnosed with atrial fibrillation and underwent 24-hour Holter monitoring.

New Methods In The Study Of Breast Cancer

New Methods In The Study Of Breast Cancer.
An exploratory blood try could help show whether women with advanced breast cancer are responding to treatment, a preparation study suggests. The test detects abnormal DNA from tumor cells circulating in the blood. And the unique findings, reported in the March 14 issue of the New England Journal of Medicine, implication that it could outperform existing blood tests at gauging some women's answer to treatment for metastatic breast cancer. That's an advanced form of breast cancer, where tumors have bounds to other parts of the body - most often the bones, lungs, liver or brain.

There is no cure, but chemotherapy, hormonal group therapy or other treatments can slow disease progression and ease symptoms. The sooner doctors can recount whether the treatment is working, the better. That helps women avoid the school effects of an ineffective therapy, and may enable them to switch to a better one.

Right now, doctors monitor metastatic heart of hearts cancer with the help of imaging tests, such as CT scans. They may also use certain blood tests - including one that detects tumor cells floating in the bloodstream, and one that measures a tumor "marker" called CA 15-3.

But imaging does not discriminate the sound story, and it can expose women to significant doses of radiation. The blood tests also have limitations and are not routinely used. "Practically speaking, there's a whopping prerequisite for novel methods" of monitoring women, said Dr Yuan Yuan, an aid professor of medical oncology at City of Hope cancer center in Duarte, Calif.

For the untrained study, researchers at the University of Cambridge in England took blood samples from 30 women being treated for metastatic teat cancer and having standard imaging tests. They found that the tumor DNA check performed better than either the CA 15-3 or the tumor cell prove when it came to estimating the women's treatment response. Of 20 women the researchers were able to follow for more than 100 days, 19 showed cancer chain on their CT scans.

And 17 of them had shown rising tumor DNA levels. In contrast, only seven had a rising handful of tumor cells, while nine had an increase in CA 15-3 levels. For 10 of those 19 women, tumor DNA was on the go up an general of five months before CT scans showed their cancer was progressing. "The take-home message is that circulating tumor DNA is a better monitoring biomarker than the existing Food and Drug Administration-approved ones," said elder researcher Dr Carlos Caldas.

Smoking And Excess Weight Can Lead To A Cancer

Smoking And Excess Weight Can Lead To A Cancer.
Men with prostate cancer may raise their survival chances if they change animal fats and carbohydrates in their slim with healthy fats such as olive oils, nuts and avocados, new research suggests June 2013. Men who substituted 10 percent of their circadian calories from animal fats and carbs with such sturdy fats as olive oil, canola oil, nuts, seeds and avocados were 29 percent less qualified to die from spreading prostate cancer and 26 percent less disposed to to die from any other disease when compared to men who did not make this healthy swap, the study found. And a not any bit seems to go a long way.

Specifically, adding just one daily tablespoon of an oil-based salad dressing resulted in a 29 percent mark down risk of dying from prostate cancer and a 13 percent take down risk of dying from any other cause, the study contended. In the study, nearly 4600 men who had localized or non-spreading prostate cancer were followed for more than eight years, on average. During the study, 1064 men died.

Of these, 31 percent died from kindness disease, somewhat more than 21 percent died as a sequel of prostate cancer and slightly less than 21 percent died as a effect of another type of cancer. The findings appeared online June 10 in JAMA Internal Medicine. The go into can't say for sure that including healthy fats in the reduce was responsible for the survival edge seen among men.

Military Personnel And Their Partners Can Not Get Quality Treatment

Military Personnel And Their Partners Can Not Get Quality Treatment.
A medical doctor with practice caring for armed forces personnel says the US military's "Don't Ask, Don't Tell" regulation puts both service members and the prevalent public at risk by encouraging secrecy about sexual health issues. "Infections go undiagnosed. Service members and their partners go untreated," Dr Kenneth Katz, a doctor at San Diego State University and the University of California at San Diego, wrote in a commentary published Dec 1, 2010 in the New England Journal of Medicine.

And civilians "pay a price" because they have mating with employ members who feel nostalgia for out on programs aimed at preventing the spread of the HIV, the virus that causes AIDS, as well as other sexually transmitted diseases. The soldiery is currently pondering the end of the "Don't Ask, Don't Tell" policy, which does not brook gay service members to serve openly. No one knows how many gays are in the armed forces. However, one 2002 scan found that active-duty Navy sailors made up 9 percent of the patients who visited one vivid men's health clinic in San Diego.
